Further, said inventlon has for its object to provide a covering or jacket of the chary acter specified which maybe provided yon its inner sides with suitable'insulatlng material. 1

` Further, said invention has for its object to provide a coveringpor` j ac ket'of the character specified having means. vrovided thereon adjacent toits free ends W ereby the same may ybe readily secured to oooperatingmeans provided upon the boiler.'

lFurther, said mvention has for, its'object I to provide a covering or jacket whichV will completely cover theportion of the boilerintermediate its -front and back sections, and form a top and side walls Wholly concealing the intermediateI sections of the boiler.

Further objects .will in part be obvious, and in part* be hereinafter pointed out.

To theattainment ofthe aforesaid objects and ends my invention consists 1n the novel.

details of construction, and in the combination, connection and .arrangement of. parts hereinafter more fully described and then pointed out in the claims In the accompanying drawings forming part of ,this specification wherein like numerals of reference indicate like parts- Figure 1 is a frontview, partly broken away, showing a boiler provided with4 one form of jacket constructed according to, and embodying my said invention;

Fig. 2 is a top view of the same partly broken away;

Fig. 3 is a side elevation partly broken away;

Fig. 6 is a detail transverse sectional view y showing a slightly modified :form of jacket -for use in connection with boilers of more than ordinary width.

In said drawings 10 designates' a boiler wliichuis herein shown as ot the sectional.V type comprising a front section 11,' aback' section. 12, and a series of intermediate-sections 13. The front section 11 is providedl with the usual flue openings, fuel openin slicing opening and ash pit opening whic are respectively provided with the usual doors 14, 15, 16 and17. n

The front sectionv 11 and the .b'acksection 12 of the-boiler are of greater outline than the intermediate sections 13 so as to provide al space at .the top vand the sides of the boiler between the outer surface of the intermediate sections 13 and the outline of the front and back sections of the boiler when thesever'al parts thereof are duly assembled. The front and back sectionsare provided upon their inwardly facing or opposing surfaces, with shoulders 11a, l2a which are arranged adjacent to the top and verticaledges of'said sections and serve partly to retain a jacket hereinafter described.

The intermediate sections 13 are provided l lnut-21 whereby the several sections 11, 12

and 13 of the boiler may be drawn together 'and secured in their assembled position.

.22 vdenotes a jacket which is preferably made of sheet metal and composed of two vsimilarly-shaped portions or sections 22,

22".' Each section or portion 22a, 22b com' prises a laterally-extending portion 23 and a vertical portion depending therefrom.

The adjacent inner edges of the laterail extending portions 23 are turned inwardly to form longitudinal iianges 24 which are engaged by the longitudinal'ianges 25 of a key or securing member 26. The ianges on vthe portion 23 which engage with the flanges on the connecting members 26 are 'so constructed'that they will allow of slight movement between the portions so that the member 26will actas a hinge connection. The

`lower edge of each vertical portion 22a, 22",

' of the jacket is provided with an inwardly turned ilange.27 which engages with the projections -18 of the Aintermediate boiler sections.

On the inner side of each section 22, 22", adjacent to its lower or free end, is provided a plurality ofA spring clips 28, each comprising aback 29, vand a pair of outwardly extending curved members or n- Y, gers 30'?l arranged in spaced relation to each other which v,are adapted to engage. with the tie-rods 20 whereby to secure the acket 22 duly in place upon the boiler.; l

The inner sides of th'e vertical portions or side members 22, 22", and the inner sides of the laterally projecting portions23 of thev jacket are provided with an insulating lining composed of sheets or layers 29 oi'as f bestos, felt or other suitable heat-lagging.

material. The said insulating layers are lof such thickness that they will substantially or nearly fill the space between the outer surfaces of the intermediate boiler sections 13 and inner surfaces of the top walls of the jacket 22.

`At Fig. 6` is shown the upper portion of a modified form of jacket 30 comprising the vangular side members 31, and an intermediate section 32 which Ymay be made inseveral widths in order to adapt the jacket to boilers of different widths. vThe edges of the laterally-extending portions 33 of the side members 31 are provided with inwardly turned edges 34, and the corresponding edges of the intermediate section 32 are provided with similarly inturned edges 35. The inner edges of the laterally-projecting portions 34, and the adjacent edges oi the intermediate Section. 32 .are secured together by keys or securing members 36 each of which has its opposite longitudinal edges turned inwardly so as to permit of a sliding engagement'thereof with the flanges 34 and 35 of the side members 31 and the intermediateand side messia without liability of injuring the jacket by reason of the hinged connection provided by the key or securing member 26.` As soon as the jacket has `been fully .adjusted between the iront section ll and backy section 12 of the boiler` thek spring-attaching memlbers 28, on t-he inner sides thereof adjacent toits lower or free edges will bein position opposite the longitudinal tie-rods 20, and

thereuponnit merely becomes necessary to' press the lower or free' ends of the vertical portions of the jacket inwardly to cause the attaching members 28 to snap into engagement with the tie-rods 2O and thereby secure the acket in position upon the boiler.

In order to remove the jacket, when it becomes necessarv to dismount the boiler orto obtainaccess thereto for any other purpose, it merely becomes necessary to grasp the lower or-free edges of the vertical' portion of the jacket and draw 'the same outwardly so that the spring-attaching members 28 may be released 4of their engagement with tierods 20 wherein theentire jacket may again be removed from the boiler.

Having thus described my invention whatv I claim and desire to secure by Letters Patent is 1. The combination with a boiler formed of a series of sect1ons,of a jacket comprising a. horizontal member and vertical side members extending therefrom, attaching means' on said jacket members, and means for secur- `ing the boiler sections together: adapted to cooperate with the attaching means on said jacket whereby to secure, said jacket in posiion upon'said boiler, substantially as speci- 2. The combination with a boiler formed of front, back and intermediate sections and means for securing the boiler sections vtogether, of a jacket comprising a U-shaped member embracing the portion of the said Iboiler intermediate its iront and back sections, andit's free edges detachably engaging the' means for securing said boiler sections.together, substantially as specified.
